The Wallace Collection were a Belgian band comprising a mix of pop musicians and members of the Belgian National Philharmonic Orchestra. He caught their show in Paris and was immediately blown away by their live show and instrumental virtuosity. They were the first band that Mackay signed upon starting with EMI in London. Their debut album Laughing Cavalier was recorded not long after and featured the hit single "Daydream" which became a hit in dozens of countries but was never really a success in the UK. It has subsequently been sampled and covered numerous times. Upon hearing the LP, George Martin said it was the best album he'd heard recorded in the Abbey Road studios that year.

New Seekers - What Have They Done To My Song Ma - Philips - 1970

After 12 months on contract as a house producer for EMI, Mackay decided to leave and set himself up as an independent operator. The very first record he made was with the New Seekers. The song was a cover of Melanie Safka's hit "What Have They Done To My Song Ma" and it found instant success making the U.S top 20 in 1970.

Bonnie Tyler - Lost In France - EMI - 1976

In 1975 some friends asked David Mackay to help finance a demo for a young singer they liked named Gaynor Sullivan. The demo was recorded, and the singer was good, but the song wasn't so great and nothing much came of it. A year later songwriters Ronnie Scott and Steve Wolfe came to him with a new song they'd written. They thought the song was a hit but didn't have a singer for it. Mackay remembered the demo singer from the previous year and suggested they try her out. By the time the single was released her name had changed to Bonnie Tyler and the song, "Lost In France", became a huge hit.

Frankie Miller - Darlin' - Chrysalis - 1979

Frankie Miller had cut a handful of album s for Chrysalis records during the 70's but had never had a big hit. Anxious to find the right sound for him his record company approached David Mackay and asked if he would have a crack at producing a record with him. Feeling that his voice had never been approached in the right way, Mackay gave him the country track Darlin' and it was an immediate success.
